To all whom it may ooncem:

Be it ki own ihei; 1, (homes GOUGHNOUR, a' c'rtizeii of the United States, and. e resident of the city of Canton, in the county of Stork: and. Stutejoifi @1150, have invented a new 22.1161 useful Improvement in Electrode Hoidexs of which the foiiowing is a speci ficstion, Z I My invention relates to devices ioi hoici ing the deem-odes of eieciziic furnaces and has for its priiicipeiobjeots to devise o i1oid or which is fififfillgf, durebie and economical, which wiii hold, eiecti'o-ries' of iiiereni, and irregular shapes mini which wiii make ciose contact wich the eiec'troiivs, ehus avoid ing areing with its attendant disadvantages of overheating the electrode-and the h'oider and preventing waiping oi the iroideiand bindmgofithe eiecirooe, end which is ad spi ed to enable electrodes to be i'emoveci and repieceii easily, quickly and without (longer to like workman, The: invention consists principally in a hinged electrode holder hoviiig :1 locking device which the use of threaded bolt The invention further consists in the parts and combine.- tioiis of. pew-V's hereinafter describefii and claimed I In time drawing which forms part of this specification om wherein ii ke refeifeiiee characters inciicaie like parts Wherever they occur,

1 is 2V plan View sin QIQCiTOKiC holder emboiying my invention;

Fig. 2 is a rear elevation thereof and 3 is a front eievgxi-ion thereof, certain m-is being broken away. My electrode holder coiiiprisss members 1 of substantially semicirculor shape hinge together. The hinge emi of one of 'seici members i has 2i tongue 2 that works in a recess 3 provided therefor in the othei of said members and a pintle i passes through hoies' in the overlapping portions of said end portions to hinge the main members of the holder together.

Diemei'ricaiiy opposite the hinge, tile hoide rf members are provided with outwerci.

1y projecting lugs o that have oiineii hoies thereth 'o'ugzii adopted to receive a locking bar 6. Said bar 6 has slots '7 therein near each end which slots are adapter)? to receive Wedges or iocking pins 8 The s'iocs 7 and ins 8 are topeirei so that, Wh%'h). i3h8 pins are riveieinto the slots, the parts the holder dispenws with motions 5 of the holder and a locking" pm 8. Washers 10 ere mounted on the iockmg bar 'ei cash end of the spring 9 to form slim memos therefor. The holder provided with suitable iugs 11o): oiher means by which it may be bolted or otherwise so cured to e brooket or simiier supporting memiieiu Prefemhiy he ifififl! siiie (ii-the eieoimie is pvovi' ezi within raised} portions 1% co flituting spacefi: contact members adopted to engage an electrode The horiy members 1 of the holder have ciienneiweys 'iiiel ethroiigh iineii' with suitabie pipe 20 and eciopted to allow water to flow through in oriioi' to coo the holder when in use. Bus bots 21 erecast in the holder" or onerwise seo oi'ed iiiei'eto in order to supply the un'ei t which holdertrensmit-s to the electrode The holder hereinbe'ifom 'diesoribed has numerous sdvamages. It;v is espeoiaily seems for holding. the carbon electrodes coiiimoniy used in eieotriefui'naoos. If one part; of the hoicier is broken, iii (35in be repieced withoiiiz the necessity of scrapping the smi e holidei: Wieh ordinary hoiers not provided with a hinge, it is necessary to s'iif the holdei" or otherwise provide a siigiit degree of elasticity so that the holder can firmly grasp the eie c'ti'ogie Thus the boldei is weakened and bieokages are frequenii. Further if, as fiequentiy is the casejhe electrode is not round, the holder will make poor contact with it, resniting in HIISEE LiSi aflOI'Y operation and ereeting shon deney for (he holder to warp and thusprevent adjustment of the eieetrocie. These disadvantages are evoicieiby my oonsimo tion. As above suggested, my hoi'der'con accommodate various sizes ofelectrodes, it is strong and dm'abie, and ,it makes better contacbwith the electrode than the holders commoniy used. Pnoviciing the holder with spaced contact, points permits the hoic'ier to sccommwfiateeiectmdes of varying sizes and irregular" shapes and minimizes the 1 tendency of the hokier to warp. The look ing deviceche'reinbefore described enables the operations of changing electrodes, tighten ing or ioosenirig the holder, lowering the" electrode in the holder and the like to zooperforated projections y and quiel i carried out, Whereas ioclrin devices that use bolls frequently burn fast to the holder and thus prevent adjust, ment of the holder and are dillicult to remove and my device also eliminates another great practical disadvantage. in the use of bolts, namely, the fact that the removal and tightening of such holts requires the 1:59

of a wreiich which is likely to slip and. cause serious accidents. The fact that the bus hare are cast in the holder prevents loss of current between the bus bars and the holder.

lVhat I claim is:

1. An electrode holder for electric furnaces coi'i'iprising substantially semi-circular ineinhcrs pivrotally secured together at one end and provided with resilient means adapted to force the free ends-of said members together, said nien'ihers having has bars cast therein to supply electric current to 1 said holder.

E 2. An electrode holder comprising members pivotally secured together, and having on their ends, aslotted locking bar passing through said holes insaid projections, locking pins in said. locking haislots, a resilient member arranged between one of said pins and one' ot' said projections, whereby said holder members are forced together,

3. An electrode holder comprising Inemhers pivotally secured together, and having perforated. projections on their free ends, a slotted locking bar passing through said holes in said projections, looking pins in said locking bar slots, and a spring arranged on said locking bar between one of said pins and one of said projections, iWhere-by said holder members are forced together.

t. An electrode holder comprising members pivotally secured together, and having perforated projections on their free ends, a slotted locking bar passing through said holes in said pro'ections, tapered locking pins in said lockixi bar slots; and a spring arranged on said locking bar between one of said pins and one of said projections, whereby said holder members are forced together.

5. An electrode holder comprising members pivotally secured together and having perforated. projections on their free ends, a locking har passing through said holes in said projections near each end thereof, tapered locking pins in said slots, and a resilient men: 5r ar ranged between one of said pins ano me of said projections.
